The Prophet ﷺ appointed Ibn Umm Maktum as his deputy over Medina to lead the people in prayer.
أن النبي ﷺ استخلف ابن أم مكتوم على المدينة يصلي بالناس.
Abu Yaala reported it in Maqsad Ali (306), and from him Bayhaqi in Marifa (5768), from Umaya bin Bistam, who said, "Yazid bin Zuray narrated to us, Habib Muallim narrated to us, from Hisham bin Urwa, from his father, from Ayesha," and he mentioned something similar.Ibn Hibban graded it sahih and reported it in his Sahih (2134), from Hasan bin Sufyan, who said, "Umaya bin Bistam narrated to us," with the same chain, in similar wording. Its isnad is hasan. Umaya bin Bistam Ayshi is "truthful," as the Hafiz said, and he is among the men of the two Shaykhs. This is why Haythami said in Majma (2328), "Abu Yaala and Tabarani reported it in Awsat, and the men of Abu Yaala are the men of the Sahih."Busiri mentioned it in Ittihaf (1603) by way of Abu Yaala and said, "This is a sahih isnad according to the standard of the two Shaykhs."
